As a follow up to an earlier post, some information about how this project went. The project was to install a tach and cruise control in a 96 Legacy (MT).
The tach was easy. Just remove the instrument cluster, add the tach and plug everything back together again. This car did not have a cable speedometer which made the job even easier.
Installing the cruise control was a bit more involved, but simple enough. The existing wiring harness had all the required plugs and connectors in all the right places. All that was missing were the various pieces. There were also some issues around the production date of our car which I will explain as well.
In the engine compartment, there were 2 main pieces to install making up the vacuum actuator - the parts that actually control the accelerator. One bolts to the firewall just behind and in line with the existing accelerator cable and the other hides over on the right side near the strut tower. A small diameter metal tube connects the two. If you're doing this, you'll need to collect the metal tube from the donor car as well.
On the steering wheel, you will need the hand control switch (resume, set, coast, cancel). Disconnect the battery, wait a few minutes, then use a Torx screwdriver to remove the steering wheel air bag. You will need to cut the opening for the switch handle to stick out through on the side of the steering wheel - the position is marked, but I had to actually cut the opening with a knife and smooth it with a file. There was also a small issue with the connector - I had to take it apart to get the wires under and around other parts in the steering wheel. Put everything back together.
While I was installing the tach, I also added the main cruise control switch. It goes just to the right of the rear window defogger switch. The wiring harness connector is there.
A switch needs to be changed on the brake pedal. Remove the brake light switch and replace it with the combined brake light -cruise control switch. There is a different connector right there for the new switch.
A switch needs to be added to the clutch pedal. Don't confuse this with the clutch start switch which is also there. I did, briefly, until I realized what was going on. Remove the bolt and nuts that adjust clutch pedal height and replace with the new switch. The needed connector is right there.
The main cruise control module can be in one of two different locations, depending on the production date of your car. One location is behind the passenger side kick panel. On our 96 Legacy, the module goes just above the clutch pedal - there are two bolt studs there to attach it and a connector to plug in. The difference here is related to the production date of the car so make sure you clarify which you're dealing with. For all I know, the modules may be the same internally, but the attachment bracket is certainly different. It took me two trips to the auto wreckers to get this sorted out. Also, according to the auto wrecker guy, there is no difference between automatic and manual transmission cruise control modules but I can't verify that.
That's it. It took me longer to find all the pieces than it did to install them, but it works just fine. I will have to adjust the cable on the actuator so the cruise takeover is smooth but the project was simple enough.
